Summary: The length of the internode on the stem of ‘Nordany2' is shorter than that of ‘Belleview' and ‘Beauregard' and longer than that of ‘Nordany1'. The diameter of the internode on the stem of ‘Nordany2' is small while that of ‘Belleview', ‘Radiance' and ‘Nordany1' are medium , and that of ‘Beauregard' is large. The leaf blade of ‘Nordany2' has seven lobes and deep lobing while ‘Belleview', ‘Radiance', and ‘Nordany1' have five lobes and moderate lobing and ‘Beauregard' has three lobes and shallow lobing. The young leaf blade of ‘Nordany2' is light green while that of ‘Radiance' is medium green, that of ‘Belleview' is light purple, and that of ‘Beauregard' is medium purple. The petiole of ‘Nordany2' has an absent or very weak intensity of anthocyanin colouration while that of ‘Beauregard' has a weak intensity and that of ‘Belleview' and ‘Radiance' have a medium intensity. The storage root of ‘Nordany2' has a moderately compressed length to width ratio while that of ‘Belleview', ‘Beauregard', and ‘Radiance' have a medium length to width ratio. The skin of the storage root of ‘Nordany2' is mainly orange while that of ‘Belleview' and ‘Beauregard' is brownish orange and that of ‘Radiance' is red.

Origin & Breeding History: 'Nordany2' originated from a cross in 2017, in Peru. The cross from which ‘Nordany1' originated was between ‘PJ05.124', as the female parent, and ‘PZ08.038', as the male parent. From the resulting progeny, approximately 800 seeds were sown in an unirrigated field in Nicolet, Quebec, Canada in 2019. In 2023, one line designated as 'Nordany2' was selected after several field evaluations in Quebec and Ontario, during the past years, for its storage root shape, tuber skin and flesh colour, yield, general appearance, and cooking and frying qualities. All field and storage evaluations at different locations in Quebec as well in Ontario were conducted by Dr. Carlos Martin.

Tests & Trials: The comparative trial for ‘Nordany2' was conducted in a field during the summer of 2025 in Lavaltrie, Quebec. The trial included a total of 50 plants each of the candidate and reference varieties. There were 2 replications per variety arranged in an RCB design. Plots consisted of 2 rows, each row 15 m long with an inter-row spacing of 0.30 metres. Observations and measurements on single plants were made on at least 30 plants. Mean differences were significant at the 5% probability level based on a t-test.
